okay so what's up guys welcome back to another video with the recent experience of oxygen os on oneplus smartphones many users nowadays give a try to custom roms based on android 12 or android 11 and after they install any custom rom we always get many messages regarding how to downgrade to stock oxygen os on their oneplus smartphones after installing custom rom so in this video we'll show you guys step by step method by which you can downgrade your device to stock oxygen os and also get back the warranty of your device which usually voids after installing custom rom so before starting the video let's keep a like target of 400 likes on this video and we still have 80 of users who haven't subscribed to our channel so it's a humble request guys do consider subscribing and also press the bell icon to get notified whenever we upload a new video and now talking about the process of getting back to stock oxygen os from any custom room basically there are two methods one is the fastboot method and the second one is using msm tool and my recommendation will always be using msm tool to downgrade a device to stock oxygen os and currently we don't have the latest fastboot roms for oneplus smartphones so whatever roms are available all of them can be found in the description below and i'll also mention all the msm ak and brick tool for every oneplus smartphone in the description below so we'll use both the methods first one will use fastboot method so if you guys are okay with fastboot method or fastboot rom then you can follow this and after that if your device doesn't boot up after installing fastboot rom then you can anytime use msm method so here i have my oneplus 7 pro which is running on paranoid android and will downgrade this device to stock oxygen os on your pc you will be requiring these many files let me tell you what are these files so here we have the unbrick tool of my oneplus 7 pro depending on your device you can download your unbrick tool for your particular device this is the fast boot rom which is based on oxygen os 10.0.6 and i could only find this one as the latest one but i'll keep updating all the fastboot roms in the description below so whenever there is new fastboot rom available for the latest android you guys can find it in the description below then we have fastboot drivers qualcomm drivers adb setup so guys these are also very important files these are the drivers of qualcomm and fastboot and i've also made a dedicated video if you guys are facing issues with unbrick tool fastboot adb just follow that video guide to install these drivers properly because once you have all these drivers properly installed on your pc you won't have any kind of issues while flashing your device using msm or using fastboot rom so to install fastboot drivers qualcomm and adb just follow this video guide which is given in the description below right click on the fastboot file and unzip this file first meanwhile what you have to do is you need to boot your device into fastboot mode so i'll also mention all the key combinations in the description below using those key combination you can easily boot your device into fastboot mode for example on my oneplus 7 pro which is running paranoid android here i get the option of booting device into fastboot mode but for those who don't get this option they can just power off the device first once the device is powered off starting from one plus series the key combination is you need to press and hold both the volume keys together and also hold the power key until you see fastboot screen once your device boots into fastboot mode connect it to pc and if you have properly installed adb or fastboot drivers then in the adb folder you can just open up command prompt and type fastboot devices to see whether your device is properly connected in fast boot mode or not and just hit enter so if you see this serial number that means your device is properly connected in fast boot mode and your pc have proper fastboot drivers installed and as said if you guys don't see the serial number or if your device doesn't get detected in the fastboot mode you can anytime follow this video guide to fix all the issues related to fastboot and adb so now let's talk about the flashing process so here we have the unzip file of fastboot rom you don't have to do anything guys just make sure you have connected your device to pc and you have proper fastboot drivers installed later you just need to double click on flash all and system will automatically take care of everything once the flashing process is completed your device should boot into system and in my case i tried fastboot rom on my oneplus 8 my device did not boot up so in this video let's try it on oneplus 7 pro and if the device boots up you are good to go if not you can just follow the msm guide which i'll show you guys once this process is completed okay so we got an error over here which says fail to extract vendor and this might happen with you guys also because currently we don't have the latest fastboot roms for oneplus smartphones but when i tried on my oneplus 8 i did not get any kind of errors everything went properly but my device did not boot up which was stuck in the fastboot mode but when we get the latest fastboot roms there are possibilities that just by using the fastboot rom we can easily revert the device back to oxygen os so this process is not working on a oneplus 7 pro but in future if it works for you guys then you can just boot your device and later lock the bootloader of your device now let's talk about the second method which is msm method aka unbrick tool currently we have almost all the latest version of msm tools so you can just download that tool and that will also be in zip file you need to right click and extract once you do that open the folder and run this file which is msm download tool version 4.0 version might change in future guys but currently for oneplus 7 pro this is the version and after that you will get a pop-up which will ask you for login so here instead of selecting factory and customer service select others and hit next and guys here once you open up the msm tool under com you should have some or the other ports for me i have com3 and after even connecting your device in emergency download mode which is edl i'll tell you how to boot your device into edl after that also if it still says anything turn off the digital signature from your windows that also i have shown in this video so make sure to follow this video guide properly to have everything working so now what we'll do is we'll disconnect the device from pc and we'll turn off the device use volume key until you see the option of power off at the top and make selection using power key once your device is powered off leave your device idle for 10 to 15 seconds and after that to boot your device into edl mode the combination is you need to press and hold volume up and down key and insert the cable so this combination is from oneplus 6 series and if you still don't understand the key combination of booting into edl mode that also i'll mention in the description below so now our device is powered off and now let's press and hold both the volume keys which is up and down and connect the device to pc so if you have properly installed fastboot drivers and qualcomm drivers under status of connection it will show you connected if it shows any then again turn off the digital driver signature so if it is connected just hit on start and now msm tool will take care of everything the entire process might take around five to seven minutes do not disconnect your device until the process is completed so let's wait for the process to get completed and we'll show you if a device boots up or not and once again guys this is one of the safest method to downgrade from any custom rom to stock oxygen os once the process is completed it will show you download completed and your device should start to boot in stock os so right now you can see a device which is oneplus 7 pro is currently booting up with oxy and os boot logo we'll wait for the device to boot up and we'll show you which oxygen os version gets installed basically oxygen os version doesn't matter because that is completely dependent on the which msm tool you are using and will also show you whether you guys will receive an ota update after using msm tool and here we go a device have been successfully booted into oxygen os and the reason why i'm saying msm tool is the safest and hassle free that's because ms stem tool will automatically relock the boot bootloader without any additional step so let's complete the initial setup and i personally will always recommend using msm tool to downgrade your device to stop oxygen os so here you can see we use the msm tool based on oxygen os 11.0.4.1 so device is now on oxygen os 11.0.4.1 i'll connect my device to wi-fi so soon i connect my device to wi-fi now i should have an ota update of the latest version for my device let's go to system update and as you can see here my oneplus 7 pro got an ota update so guys these are the two methods by which you can downgrade your any oneplus smartphone from custom rom to oxygen os stock rom but as said my recommendation will be always use msm tool to downgrade your device you guys must have already seen in this video for us fastboot rom did not work and that might work when we have the latest fastboot rooms currently with the present fast boot roms you guys might face some of the other issues so guys this was a quick look on how to install stock os on your oneplus smartphones if you are running custom rom if you still have any kind of questions you can anytime join a
